Application filed July 1, 1910. serial No. 569,969.

To all whom it may 002-20 17), 3

Be 1t known that Fns ros S. RAN-u, a

citizen oi the Unite-cl States, residing at l rovidenee, in the county of Providenceand Stateoi Rhode Island, have invented certain new useful Improvements in Warpingliiachines, of which the following is a specification.

hiy invention relates to improvements in warping or beaming n'iachines employed in winding yarn in multiple from'ereels or other supply stands on to warp or sectionbeams, and has for its ohject'to increase the speed of operation of the machine and produee a more perfect beam with the yarn mass disposed concentrically about the axis oi the latter. I

My invention consists particularly of dog' ging mechanism adapted to regulate the pressure of the yarn mass on its driving roll or drum so that the beam can be rotated at high speed without vibration or poundand the yarn wound on more evenly without ridges or eccentric-places.

The invention is fully set forth in the fol-,

lowing specification, iliust-rated by the aceompanyin'g drawings, in which Figure 1 is'a front elevation of a usual form ofwarping or beaming machine, with my improvement shown applied thereto; Fig. 2, a side elevation of the same; Fig. 3, an enlarged, detailed sectional view of the dogging device showing the locking mechanism released; Fig an'end'elevation of the same; Fig. 5, a sectional view similar to Fig. 3, with the locking mechanism shown inoperative position; Fig. 6, an enlarged sectional elevation showing a modification of the dogging mechanism; Fig. 7, an end elevation of the same.

Figs. 1 and 2 illustrate a usual form of warping or beaming machine adapted for winding yarns in multiple from a creel or othersupply-holder on to a warpor seetion-beam. The machine consists essentiaily of two upright frames A at either end, carrying suitable hea a in which the driving shatt C is rot-ate 1y mounted. The shaft C carries a drivingwoll or drum D arranged between the two end frames of,

the machine and adapted to bear on the barrel (3 of the ham B to rotate the latter hy frictional contact 'wiitli'i th dyh'rird wionndt' the eon.

- secured i the 1 present improvement contemplates means for controlling the movement of the beam toward and away from't-he driving drum arranged to apply the dogging action at points near the axis of the drum so that it will be more eti'ectivein regulating the movement of the drum on its swinging arms.

As shown in Figs. 1 and 2, I provide suit able bearings or sta-ndardsG which are preferably fastened to the floor bet-ween the end frames of the warping machin'el Secured in these bearings is a horizontal rod or-shaft H, held by the set screws f, see Fig. 2,-and mountedonthe ends of,' this shaft are two upright, swiveled staves or rods Fheld in the arms f which are pivoted on the shaft.

The rods-F extend-upward adjacent the gudgeons of the beam B, and the bushings b", which erve as bearings for the beam, are

ii brackets Euvh'ich slide on the rods F. The brackets-l3 are formed with sockets for the bushings. and the latter are held in place by the pins 6, as illustrated in Fig. 3. At thelower end of each bracket E is an opening or slot e in which is located a dogging'anember I" which surrounds the rod The li od F' is preferably of 'squarefsection and the member I has a angle to the hole 2'.

square bore iwhic-h gis jslightly larger than the dimensions of the rod. Y This bore runs straight through the member, and a second square hole 2' is formed inthe nut at an This second bore or hole 2' isof less width than the thickness of the" rod F, so that when the member is tipped or canted the sides of this hole will impinge upon therod and give a wedging grip on the latter Preferably, the top and bottom sideswof the member I, are rounded Off at i and 2" so that the member will rock easily on its bearing against thesides of the slot in thebracket E. At the lower end of the bracket E isa pocket e? inw'hich is lo;

cated a sliding plu'ngerJ, the upper end of which'ibear s on one side of the lower face -of the member I. A coiled spring 7', held L is operated bya finger pin 1' which serves as a lever to turn the cam Z down against the member I, to hold the latter against the action of the spring plunger J, as shown in Fig. I V

The operation of the above described arrangement is as follows: The bushings b are placed on the gudgeons I) of the empty 'beam and slid into the bearings at the ends of the arms '1). The brackets E are next v the bushings.

periphery of themass; but vice'versa, when tance'fromthe axis of the beam, will be slid up on the rods F and the rods swung outward to adapt the brackets to fit around The bushings are then se-; cured in position inthe brackets by means of the pins e. The 0am I is turned down m.

' onto themember I torelease the latter'from engiigement with the rod' F. so that the] bracket Ecan be adjusted up and down the rod. When the beam is'in pos'itionthe cam l is disengaged from the'member I by turning the lever l andthe plunger J will then act to tilt the memberI and'cau'seit to bind on the'rod Fy ns the y m is ,wfoundqon to the barrel of the bean B .the latter will rise on its arms. 6, and the brackets E adapt'themselves to this movementby slid ing upward on the rods F; It will be seen that upward movement of? the bracket E tends to straighten the position of the membcr' I: onthe rod F soth'at the bracket is allowed to slide freely, Movement of the bracket E in the'dpposite direction, how-' ,ever,-that is, downward on the rodw ill be resisted by the member I, because such movement tends to augment the effect of the plunger towcramp the member against the rod. .In other words, with the device ad usted as shown in Fig. 5 the bracket 'E is free to move upward on the rod F but is prevented from downward movement by the The pivotal mounting of the stav es or rods F on the standards G provides fora tilting movement 'of the rods'. to accommodate the brackets Eto'the arcual movementof the bearings of the beam B on its arms 6 1- The cffectof this action'on the beam B is to prevent it from returning'toward the driving drun l) after it has once been'carried upward. Itwill be seen that it the barrel of the beam is eccentric or out of true, the latter .will rise to'accommodate the high place on its periphery, and underv ordinary circumstances the bean woul d fall again lVit hfthe present arrangement the beam is held from moving back toward the drum after it has once been raised, and this action has a tendency to, regulate the laying of the yarn so that the mass will be wound more nearly concentric about the axis of the beam.

The effect willbe'to relieve the pressure of V the weights 1) on the beam when the w1n,ding is being done on. a low place on the a high place on the periphery is bearing on the driving drum the weights will act with their utmost force. In this way the high places, that is, the places of greatest dis}:

r25 pressed down and wound more compactly, while on the low places the pressure is. re-

moved so that the yarn will not be wound so hard. and will therefore build hp more nearly to the true circumference of the whole mass. The dogging action further prevents the jmnping and pounding of the beam on its driving drum, and as the beam is wound more nearly two, peripherally, its speed of rotation can he maintained at a higher rate and therefore the production of the machine is materially increased.

In F (3 and 7 is shown a modification of the dogging mechanism proper, which acts in substantially the same manner as that described above and produces the same effect At the li'mercnd of the bracket E is a vertically disposed slot- 6 in which is positioned a can: M mounted on the stud or shaft N, and secured by the set screw m. The stud N is mounted rot rely in bearings in the bracket 1, and at me of its ends is secured a weighted lever {l which serves as a handle for operating ti 1 cam M. The

serves to eti'cct a bin; tween the cam and i'he rod in position a1; shown by 1 lines in Fig. 6, the bracket is free to he moved dmvnward on the rod F to ad it to a position to receive the bushing of the unfilled beam. After the beam is in place with its bearings in the arms 3) and the bushings secured in the brackets E the levers O are swung over to the position illustrated by full lines in Fig. 6. With the cams M in this pwsn the upward. movement of the brackets E will be unrestricted. but downward movement. will be prevented by the cttcct of the cams binding against. he rods F. In this way the cams M serve the same purpose as the members I in the previously described ar angement, and the beam is prevented from vibrating up and down and pounding on its driving drum.

It..\'lll be seen that my improved device provides a simple and etlicient means for controlling the movement of the beam away from its driving, drum to prevent undue vibration or pounding of the beam and to provide for winding on the yarn in a concentric mass The present arrangement shows meritorius improvement in that the dogging action' is applied on both ends of the beam at points adjacent the bearings of the latter, so that the beam is held more positively and rigidly and there is no chance tor play. Furthermore, the dogging mechanism is convenient of access and the locking device can be released by simply turning a small finger lever so that the beam can be placed in position and removed very readily and expeditiously.

It. will be evident that various modifications might be made in the structure and arrangement of my 'oved device without departing from the pirit and scope of the invention.
